• TROUBLESHOOTING
English
Protector circuit
The HCU-R30E is equipped with a high speed protector circuit.
This circuit protects internal parts from being damaged by strong currents generated in the unit should the unit be
operated when the speaker terminals are incompletely connected or short circuited.
If this protector circuit is activated, a relay sound is produced, the output to the speakers is interrupted, and the
indicator blinks rapidly to indicate that there is a problem. If this should happen, unplug the power cord, and contact
your store of purchase.
The unit may not operate properly due to such external influences such as lightning or static electricity. If this
happens, either turn off the power with the power operation switch or unplug the power cord, wait approximately 5
seconds, then plug the power cord back in.
